This document:
a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; outlines the interoperability issues for city domain information models;
b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; reviews relevant standards and best practices and examines methodologies or solutions to tackle the interoperability issues;
c)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; supposes a use case and provides an example to secure interoperability among different domain information models using model registry;
d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; specifies technical requirements in concern about how to apply the interoperability elements of the meta model framework to support the interoperability of smart city services;
e)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; highlights the standardization items to be developed to secure interoperability.</td>
